We stayed in this place for a week with 2 adults and 4children. The location is brilliant as it's in the very quiet side street, but very close to Sukhumvit (1 min by walk). You can reach ice-skating ring or bounce center or best shopping mall just walking around. The metro station is also very close.
The house itself is spacious and comfortable if you are ok to use the stairs, because it has 4 floors. Many bedrooms with comfortable beds, cozy living room with a big dining table and efficient aircons in every room as well as very clean bathrooms. The kitchen isn't big, but very well equipped -you'll find everything you need for cooking.
What we like a lot is a pool table. It's in excellent condition, by the way. It was such a great thing for an evening after long day in the city.
There is no special parking lot near the house, but on the host's advice we parked our car right near the entrance as there's enough space there.
The host was very helpful during our stay and especially after, as we forgot some important things inside the house - everything was sent by mail very quickly.
So overall it was an amazing stay and we definitely stay again when we are in Bangkok.
